Accounting Policies [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Nature of Operations National Vision Holdings, Inc. ( “NVHI,” the “Company,” “we,” “our,” or “us”) is a holding company whose operating subsidiaries include its indirect wholly owned subsidiary, National Vision, Inc. (“NVI”) and NVI’s direct wholly owned subsidiaries. The Company is a leading value retailer of eyeglasses and value retailer of contact lenses. To support our operations, we also own and operate three optical laboratories and two distribution centers. We operated 996 and 943 retail optical locations in the United States and its territories as of September 30, 2017 and December 31, 2016, respectively, through our five store brands, America’s Best Contacts and Eyeglasses (“America’s Best”), Eyeglass World, Vista Optical locations on U.S. Army/Air Force military bases and within Fred Meyer stores, and our management & services arrangement with Walmart. Basis of Presentation The accompanying condensed consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and, therefore, do not include all information and footnotes required by U.S. GAAP for complete consolidated financial statements. The condensed consolidated balance sheet as of December 31, 2016 has been derived from the audited consolidated balance sheet for the fiscal year then ended. These unaudited interim condensed consolidated financial statements reflect all normal and recurring adjustments which are, in the opinion of management, necessary to present fairly the Company’s consolidated financial position as of September 30, 2017, the consolidated results of operations for the three and nine months ended September 30, 2017 and October 1, 2016, and consolidated cash flows for the nine months ended September 30, 2017 and October 1, 2016. Certain information and footnote disclosures normally included in our annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted; however, we believe that the disclosures included herein are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto for the fiscal year ended December 31, 2016 included in the Company’s final prospectus dated October 25, 2017 (the “Prospectus”), as filed with the Securities and Exchange Commission (the “SEC”) on October 27, 2017 pursuant to Rule 424(b)(4) under the Securities Act Securities Act of 1933, as amended (the “Securities Act”). The significant accounting policies followed by the Company are set forth in Note 1 within those consolidated financial statements. We use the same accounting policies in preparing interim condensed consolidated financial information and annual consolidated financial statements. There were no changes in our significant accounting policies during the nine months ended September 30, 2017, except for the adoption of Accounting Standards Update (“ASU”) No. 2016-09, Improvements to Employee Share-Based Payment Accounting and ASU No. 2017-04, Intangibles - Goodwill and Other, neither of which had a material effect on the Company’s consolidated financial condition, results of operations, or cash flows. The condensed consolidated financial statements include our accounts and those of our subsidiaries, all of which are wholly-owned. All intercompany balances and transactions have been eliminated in consolidation. Fiscal Year Our fiscal year consists of 52 or 53 weeks ending on the Saturday closest to December 31. Fiscal year 2017 contains 52 weeks and will end on December 30, 2017. All three and nine month periods presented herein contain 13 and 39 weeks, respectively. All references to years and quarters relate to fiscal periods rather than calendar periods. Seasonality The consolidated results of operations for the three and nine months ended September 30, 2017 and October 1, 2016 are not necessarily indicative of the results to be expected for the full fiscal year due to seasonality and uncertainty of general economic conditions that may impact our key end markets. Historically, our business has realized a higher portion of net revenue, income from operations, and cash flows from operations in the first fiscal quarter, and a lower portion of net revenue, income from operations, and cash flows from operations in the fourth fiscal quarter. The seasonally larger first quarter is attributable primarily to the timing of our customers’ personal income tax refunds and annual health insurance program start or reset periods. Seasonality related to fourth quarter holiday spending by retail customers does not significantly impact our business. Our quarterly consolidated results can also be affected by the timing of new store openings and store closings and the timing of certain holidays. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Initial Public Offering On October 30, 2017, we completed an initial public offering of our common stock (“IPO”) in which we issued and sold 18,170,000 shares of common stock, including 2,370,000 shares of common stock pursuant to the exercise in full of the underwriters’ option to purchase additional shares. The shares sold in the offering were registered under the Securities Act pursuant to our Registration Statement on Form S-1 (File No. 333-220719), which was declared effective by the SEC on October 25, 2017. The shares of our common stock were sold at an initial offering price of $22.00 per share, which generated net proceeds of approximately $375.8 million to the Company, after deducting underwriting discounts and commissions of approximately $24.0 million which included $0.7 million paid to KKR Capital Markets LLC. (“KCM”), an affiliate of KKR, for underwriting services in connection with the IPO. We primarily used the net proceeds from the IPO to repay all $125.0 million outstanding aggregate amount of the Company’s second lien term loans and approximately $235.0 million of the outstanding amount of the Company’s first lien term loans and accrued and unpaid interest thereon. The repayment will result in an extinguishment of debt in the amount of approximately $353.3 million, which will be recognized in the fourth quarter of 2017. During the fourth quarter of 2017, the Company expects to pay $4.0 million of transaction related expenses. The remaining $11.8 million of the proceeds will be used for general corporate purposes, including the termination fees described below. NVI was party to a Monitoring Agreement, dated as of March 13, 2014 (the “Monitoring Agreement”), with KKR and Berkshire, which was terminated automatically in accordance with its terms upon the completion of the IPO. In connection with such termination, the Company paid termination fees of approximately $3.6 million and $0.8 million to KKR and Berkshire, respectively. Affiliates of KKR and Berkshire retained 58.2% and 13.6% ownership interest, respectively, in the Company after the IPO. Stock Split In connection with preparing for the IPO, on October 12, 2017 the Company’s Board of Directors approved a 1.96627-for-one reverse stock split of the Company’s common stock. The reverse stock split became effective October 24, 2017. The par value per share of common stock and authorized shares of common stock remain unchanged at $0.01 per share and 200 million shares, respectively. The accompanying financial statements and notes thereto give retroactive effect to the reverse stock split for all periods presented. All common share and per share amounts in the financial statements and notes have been retrospectively adjusted to give effect to the reverse stock split, including reclassifying an amount equal to the reduction in aggregate par value of ‘‘Common stock’’ to ‘‘additional paid-in capital’’ on the condensed consolidated balance sheets. Deferred Offering Costs We capitalize legal and accounting fees directly relating to the IPO. These deferred offering costs will be offset against offering proceeds during the fourth fiscal quarter of 2017. As of September 30, 2017, the Company capitalized $3.2 million of deferred offering costs in prepaid expenses and other current assets in its condensed consolidated balance sheet, and accrued $2.7 million of such costs during the nine months ended September 30, 2017, which are presented in the condensed consolidated statement of cash flows as non-cash financing activities for the nine months ended September 30, 2017. We estimate an additional $1.6 million of direct IPO related costs to be capitalized in the fourth quarter of 2017. We also estimate to record an increase in additional paid-in-capital of $371.0 million as a result of the IPO. Income Taxes Our effective income tax rate, or ETR, was 9.5% and 34.1% during three moths ended and 35.2% and 39.4% during the nine months ended September 30, 2017 and October 1, 2016, respectively. The 9.5% rate during the three months ended September 30, 2017 resulted from a change to our expected annual ETR, with the cumulative results of that change recorded in the current quarter. During the nine months ended September 30, 2017, our expected combined statutory federal and state rate was reduced by a $1.4 million income tax benefit (5.3%) resulting from the recapitalization dividend described in Note 5 - Related Party Transactions. Other items aggregated to a 0.5% further reduction in the rate for the period. These benefits were partially offset by an increase in tax expense of $0.4 million (1.5%) related to a valuation allowance recorded on an impairment-related deferred tax asset. Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers, to clarify the principles used to recognize revenue for all entities. ASU No. 2014-09 provides new guidance related to the core principle that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance also will result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively, and improve guidance for multiple-element arrangements. During 2016, the FASB issued additional ASUs to clarify certain aspects of ASU No. 2014-09, including ASU No. 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) in March 2016, and ASU No. 2016-10, Identifying Performance Obligations and Licensing in April 2016. The guidance is effective for fiscal years beginning after December 15, 2017, and interim reporting periods within that fiscal year. The Company will adopt this new guidance in the first quarter of 2018 using the modified retrospective method. The most significant components of the new guidance to the Company relate to performance obligations surrounding our bundled product and service offerings and the reporting of revenue on a gross versus net basis with respect to our management and services agreement with Walmart, and the timing of revenue recognition associated with our discount club membership fees. We are currently finalizing our assessment, but we do not expect the adoption of this new guidance to have a significant impact on the timing or amount of revenue recognized in our consolidated financial results based on our implementation progress to-date. We do expect incremental additional disclosures in the notes to our consolidated financial statements. In February 2016, FASB issued ASU No. 2016-02, Leases. The new guidance establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either financing or operating, with such classification affecting the pattern of expense recognition in the statement of operations. The guidance is effective for fiscal years beginning after December 15, 2018, and interim reporting periods within that fiscal year. A modified transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company will adopt this new guidance in the first quarter of 2019. We are evaluating the impact of implementation of this new guidance on our consolidated financial statements, but expect that adoption will have a material impact to the Company’s total assets and liabilities since we have a significant number of operating leases not currently recognized on our consolidated balance sheets. In April 2016, FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. This new guidance simplifies the accounting for share-based payment transactions, including income tax consequences, classification of certain items on the statement of cash flows, forfeitures, and minimum statutory withholding requirements. This new guidance is effective for fiscal years beginning after December 15, 2016, and interim reporting periods within that fiscal year. We adopted this new guidance in the first quarter of 2017. The adoption of this new guidance did not have a material effect on the Company’s financial condition, results of operations, or cash flows. In January 2017, FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other. This new guidance removes Step 2 of the goodwill impairment test. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The new guidance will be applied prospectively, and is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We adopted this new guidance during the first quarter of 2017. The adoption of this new guidance did not have a material effect on the Company’s financial condition, results of operations, or cash flows. Correction of an Error During the first quarter of 2017, we identified an error in our previously issued 2016 consolidated financial statements related to contact lens inventories that were expired or expiring and could not be sold as of December 31, 2016. Fiscal year 2016 costs applicable to revenue (products) was understated by $2.1 million, and net income was overstated by $1.3 million. We corrected the error in the three months ended July 1, 2017. Management concluded that the error was not material to the 2016 consolidated financial statements or the estimated 2017 results of operations. Cost Method Investment The Company has a $1.0 million cost method investment in a private start-up company whose principal business is creating eyeglasses through three dimensional printing which can be customized based on a scan of the customer’s face. During the second quarter of 2017, management determined that it was unlikely that the business would be able to continue operations for the foreseeable future. Therefore, we recorded an impairment charge for the entire amount of the investment during the second quarter of 2017, which is reflected in the condensed consolidated statement of operations and other comprehensive income for the nine months ended September 30, 2017.

Fair Value Disclosures [Abstract]

Fair Value Measurements of Financial Assets and Liabilities

The Company uses a fair value hierarchy that is intended to increase consistency and comparability in fair value measurements and related disclosures. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources while unobservable inputs reflect pricing based upon a reporting entity’s own market assumptions.

Under U.S. GAAP, the Company is required to (a) measure certain assets and liabilities at fair value or (b) disclose the fair values of certain assets and liabilities recorded at cost. Accounting standards define fair value as the price that would be received upon sale of an asset or paid upon transfer of a liability in an orderly transaction between market participants at the measurement date. Fair value is estimated assuming the transaction occurs in the principal or most advantageous market for the asset or liability and includes consideration of non-performance risk and credit risk of both parties. A three-tier fair value hierarchy prioritizes the inputs used in measuring fair value. These tiers include:

• Level 1 - Valuation inputs are based upon unadjusted quoted prices for identical instruments traded in active markets.

• Level 2 - Valuation inputs are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in inactive markets, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

• Level 3 - Valuation inputs are unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are determined using model-based techniques that include option pricing models, discounted cash flow models and similar techniques.

The fair value estimates of financial instruments are not necessarily indicative of the amounts we might pay or receive in actual market transactions. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts.

Cash and Cash Equivalents

The carrying amount of cash and cash equivalents approximates fair value due to the short term maturity of the instruments. All cash and cash equivalents are denominated in U.S. currency.

Accounts Receivable

The carrying amount of accounts receivable approximates fair value due to the short-term nature of those items and the effect of related allowances for doubtful accounts.

Accounts Payable and Other Payables and Accrued Expenses

The carrying amounts of accounts payable and other payables and accrued expenses approximate fair value due to the short-term nature of those items.

Long-term Debt - Credit Agreements

Our long-term debt is traded in private markets on a less-than-daily basis. Fair value is based on the average of trading prices and bid/ask quotes around period-end (Level 2 inputs). The estimated fair values of our combined First and Second Lien Term Loans were $928.8 million and $753.0 million as of September 30, 2017 and December 31, 2016, respectively, compared to carrying values of $913.5 million and $742.9 million, which includes the current portion, and is net of unamortized discounts and deferred debt issuance costs. See Note 6 - Debt for further information related to debt transactions recorded during the three and nine months ended September 30, 2017.

Long-term Debt - Capital Leases

The fair value of capital lease obligations is based on estimated future contractual cash flows discounted at an appropriate market rate of interest (Level 2 inputs). The estimated fair values of our capital leases were $10.6 million and $2.9 million as of September 30, 2017 and December 31, 2016, respectively, compared to carrying values of $8.9 million and $2.7 million, respectively.

Interest Rate Derivatives

The Company is a party to three pay-fixed and receive-floating interest rate swap agreements to offset the variability of cash flows in LIBOR-indexed debt interest payments attributable to changes in the benchmark interest rate from March 13, 2017 to March 13, 2021 related to its current First Lien Credit Agreement. The Company designated these swap agreements as cash flow hedges at inception. Changes in the cash flows of each derivative are expected to be highly effective in offsetting the changes in interest payments on a principal balance equal to the derivative’s notional amount, attributable to the hedged risk. We have not had any ineffectiveness related to these instruments since inception.

We recognize as assets or liabilities at fair value the estimated amounts we would receive or pay upon a termination of interest rate swaps prior to their scheduled expiration dates. We record the period change in fair value of cash flow hedges, net of tax, in the accompanying condensed consolidated statements of comprehensive income and the cumulative change in fair value of cash flow hedges since inception, net of tax, in accumulated other comprehensive loss (“AOCL”) in the accompanying condensed consolidated balances sheets. Fair value is based on information that is model-driven and whose inputs are observable (Level 2 inputs).

Our cash flow hedge position related to interest rate derivative contracts is as follows:



In thousands	Notional Amount		Final Maturity Date	Other Payables and Accrued Expenses		Other Liabilities		AOCL, Net of Tax
As of September 30, 2017	$	500,000	March 2021	$	8,499	$	13,061	$	13,223
As of December 31, 2016	$	500,000	March 2021	$	8,218	$	15,518	$	14,556

As of September 30, 2017, the Company expects to reclassify $8.5 million of AOCL into earnings in the next 12 months. See Note 11- Accumulated Other Comprehensive Loss. Subsequent to the nine months ended September 30, 2017, the Company used proceeds in connection with the IPO to reduce outstanding debt. This event did not have a material impact on the hedge position for the nine months ended September 30, 2017 and is not expected to have an impact on the hedge position for the remainder of 2017. See Note 12 - Subsequent Events for transactions in connection with the IPO.

Stock Incentive Plan

2014 Stock Incentive Plan

In 2014, our Board of Directors and stockholders of the Company approved the 2014 Stock Incentive Plan for Key Employees of NVHI (previously known as Nautilus Parent, Inc.) and Subsidiaries (the “2014 Stock Incentive Plan”). The 2014 Stock Incentive Plan was subsequently amended by our Board of Directors and our stockholders on November 9, 2015 and June 5, 2017 to increase the share reserve. The 2014 Stock Incentive Plan provides for the grant of stock options and other stock-based awards to employees, non-employee members of our Board of Directors, consultants, and other persons having a service relationship with us. We have reserved an aggregate of 10,988,827 shares of our common stock for issuance under our 2014 Stock Incentive Plan. As of September 30, 2017, options to purchase a total of 10,347,067 shares of common stock were issued and outstanding (excluding rollover options), 565,860 shares of common stock had been issued upon the exercise of options and 69,452 shares remained available for future grants.

The following presents a roll-forward of stock options, giving retroactive effect to the reverse stock split, for the nine months ended September 30, 2017:



Options issued and outstanding	Vested Rollover	Service-Based		Performance-Based	Total

Balance, September 30, 2017	169,050	1,582,256		—	1,751,306

The total estimated fair value of service-based options granted during the nine months ended September 30, 2017 was $4.6 million. During the same period, there were 16,274, 36,618, and 158,676 service-based options exercised at a price of $9.24 per share, $7.24 per share, and $4.27 per share, respectively, for a total intrinsic value of $1.5 million. As a result of the application of ASU No. 2016-09, the Company recorded an income tax benefit of $0.2 million in the condensed consolidated statement of operations and comprehensive income related to these exercises. There was no additional significant activity for the three months ended September 30, 2017.

The fair value of service-based options vested and outstanding as of September 30, 2017 was $9.4 million. The remaining unrecognized service cost for service-based options was $7.6 million as of September 30, 2017.

Compensation expense associated with service-based stock options is presented in selling, general, and administrative expenses (“SG&A”) in the accompanying condensed consolidated statements of operations and comprehensive income. The vesting of performance-based options is conditional upon the achievement by the majority stockholder in NVHI, KKR, with respect to its investment in NVHI, of both a minimum internal rate of return and a minimum multiple of invested capital and then increases proportionally as the multiple of invested capital increases up to a defined target. No compensation expense has been recorded in relation to performance based options since achievement of the conditions triggering vesting by the IPO, or otherwise, have not been deemed to be probable as of September 30, 2017.

See Note 12 - Subsequent Events for information about the adoption of a new omnibus incentive plan and related equity compensation matters in connection with the IPO.

See Note 1 - Description of Business and Basis of Presentation for further details regarding transactions with our equity sponsors in conjunction with and following the IPO.

Dividend & Stockholders’ Equity

On February 2, 2017, the Company declared a recapitalization dividend to its stockholders, which included KKR, Berkshire, and management. Common stockholders received a dividend per common share of $1.51. There were 110.5 million common shares outstanding and eligible for the dividend. Vested and roll-over option holders received an additional cash payment of $1.51 per option, for an aggregate payment of $3.7 million. The income tax benefit of the additional cash payment was $1.4 million, which was incurred in the first quarter of 2017, is included in the condensed consolidated statement of operations and comprehensive income for the nine months ended September 30, 2017. The exercise price of unvested options was reduced by $1.51 per option, the amount of the dividend. Since the Company was in an accumulated deficit position on the date of declaration of the dividend, according to our accounting policy the combined total cash payment of $171.0 million was recorded as a reduction to additional paid-in capital. No other material non-recurring charges were recorded to stockholders’ equity during the three and nine months ended September 30, 2017.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies From time to time, the Company is involved in various legal proceedings incidental to its business. The Company reviews the status of its legal proceedings and records a provision for a liability when it is considered probable that both a liability has been incurred and the amount of the loss can be reasonably estimated. The Company’s subsidiary, FirstSight Vision Services, Inc. (“FirstSight”) is a defendant, in a purported class action in the U.S. District Court for the Southern District of California that alleges that FirstSight participated in arrangements that caused the illegal delivery of eye examinations and that FirstSight thereby violated, among other laws, the corporate practice of optometry and the unfair competition and false advertising laws of California. On March 23, 2017, the court granted the motion to dismiss previously filed by FirstSight and dismissed the complaint with prejudice. The plaintiffs filed an appeal to the U.S. Court of Appeals for the Ninth Circuit in April 2017. The Company believes that the claims are without merit. In May 2017, a complaint was filed against the Company and other defendants alleging, on behalf of a proposed class of consumers who purchased contact lenses online, that 1-800 Contacts, Inc. entered into a series of agreements with the other defendants, including the Company’s subsidiary, Arlington Contact Lens Service, Inc. (“AC Lens”), to suppress certain online advertising and that each defendant thereby engaged in anticompetitive conduct in violation of the Sherman Antitrust Act (the “1-800 Contacts Matter”). The Company has settled the 1-800 Contacts Matter for $7.0 million, without admitting liability. Accordingly, the Company recorded a $7.0 million charge in litigation settlement in the accompanying condensed consolidated statement of operations and comprehensive income during the nine months ended September 30, 2017, which were incurred in the second quarter of 2017. See Note 12 - Subsequent Events.

Segment Reporting

Segment Reporting [Abstract]

Segment Reporting

The Company’s reportable segments were determined on the same basis as used by the Chief Operating Decision Maker (“CODM”) to evaluate performance internally. Our operations consist of two reportable segments:

• Owned & host store brands - Our owned brands consist of our America’s Best and Eyeglass World operating segments. Our host brands consist of our Vista Optical operating segments at certain U.S. Military Branches and inside Fred Meyer stores. We have aggregated our owned and host operating segments into a single reportable segment due to similar economic characteristics and similarity of the nature of products and services, production processes, class of customers, regulatory environment, and distribution methods of those brands.

• Legacy - The Company manages the operations of 227 legacy retail vision centers within Walmart stores. We earn management fees as a result of providing such services and therefore we record revenue related to sales of products and product protection plans to our legacy partner’s customers on a net basis. We also sell to our legacy partner wholesale merchandise that is stocked in retail locations, and provide central lab processing services for the finished eyeglasses and frames expected to be sold to our legacy partner’s customers. We lease space from our legacy partner within or adjacent to each of the locations we manage and use this space for the provision of optometric examination services. Our legacy agreements were renewed on January 13, 2017, and expire on August 23, 2020, subject to extension pursuant to the terms of the agreements. Sales of services and plans in our legacy segment consist of fees earned for managing the operations of our legacy partner and revenues associated with the provision of eye exams. Revenue associated with managing operations of our legacy partner were $9.1 million and $28.3 million for the three and nine months ended September 30, 2017 and $9.7 million and $29.9 million for the three and nine months ended October 1, 2016, respectively.

The “Corporate/Other” category includes the results of operations of our other operating segments and corporate overhead support. The “Reconciliations” category represents other adjustments to reportable segment results necessary for the presentation of consolidated financial results in accordance with U.S. GAAP for the two reportable segments.

Revenues from the Corporate/Other segments are attributable to the AC Lens, and FirstSight operating segments and the Company’s corporate function. AC Lens sells contact lenses and optical accessory products to retail customers through e-commerce. AC Lens also distributes contact lenses to Walmart and Sam’s Club under fee for services arrangements. FirstSight sells single service health plans in connection with the operations of America’s Best in California, arranges for the provision of eye exams at retail locations throughout California and also sells contact lenses to its members in certain locations. None of those segments met the quantitative thresholds for determining reportable segments for any of the periods presented.

Our reportable segment profit measure is EBITDA, or net revenue, less cost applicable to revenue, less selling, general and administrative costs. Asset impairment, depreciation and amortization, and other corporate costs that are not allocated to the segments, including interest expense, debt issuance costs and litigation settlements, are excluded from segment EBITDA. There are no transactions between our reportable segments. There are no differences between the measurement of our reportable segments’ assets and consolidated assets. There have been no changes from prior periods in the measurement methods used to determine reportable segment profit or loss, and there have been no asymmetrical allocations to segments.

The following is a summary of certain financial data for each of our segments. Reportable segment information is presented on the same basis as our condensed consolidated financial statements, except for net revenue, which is presented on a cash basis, excluding the effects of unearned and deferred revenue, consistent with the basis on which the CODM regularly reviews performance segments. Asset information is not included in the following summary since the CODM does not regularly review such information for the reportable segments.

Earnings Per Share [Abstract]

Earnings Per Share

Basic earnings per share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted EPS is computed by dividing net income by the weighted average shares outstanding for the period and include the dilutive impact of potential new shares issuable upon exercise of stock options and vesting of restricted stock units. Potentially dilutive securities are excluded from the computation of diluted EPS if their effect is anti-dilutive. A reconciliation of the numerators and denominators of the basic and diluted EPS calculations is as follows:

Stock Split Effective October 24, 2017, the Company effected a 1.96627-for-one reverse stock split of the Company’s common stock. See Note 1 - Description of Business and Basis of Presentation for disclosure related to the Company’s reverse stock split. 2017 Omnibus Incentive Plan In connection with the IPO, on October 23, 2017 the Company’s Board of Directors adopted, and its stockholders approved, the National Vision Holdings, Inc. 2017 Omnibus Incentive Plan (the “2017 Omnibus Incentive Plan”). The 2017 Omnibus Incentive Plan provides that the total number of shares of common stock that may be issued under the plan is 4,000,000. Under the plan, we may grant stock options, stock appreciation rights, restricted stock, restricted stock units, other equity-based awards and other cash-based awards to our employees, directors, officers, consultants and advisors. Additional information about the 2017 Omnibus Incentive Plan is included in the Prospectus, see “Management-Executive Compensation-Narrative to Summary Compensation Table and 2016 Grants of Plan-Based Awards-Equity Incentive Plans.” October 2017 Issuances of Restricted Stock Units and Stock Options Effective October 25, 2017, we granted stock options to purchase 92,443 shares of our common stock at $22.00 per share to an employee under the 2017 Omnibus Incentive Plan. The stock options will vest in three equal installments on the first, second and third anniversary of the grant date. Non-cash stock based compensation expense associated with the grant will be approximately $0.8 million expensed over three years.

KCM, Goldman Sachs Bank USA and Merrill Lynch, Pierce, Fenner & Smith Incorporated acted as joint lead arrangers with respect to the joinder and amendment agreement and in aggregate received fees of $0.7 million, of which $0.3 million was received by KCM.

First Lien Credit Agreement - Joinder and Amendment Agreement On November 20, 2017, the Credit Agreement was amended pursuant to a joinder and amendment agreement to, among other things, (a) establish new first lien term loans in an aggregate principal amount of $570.0 million to refinance all of the first lien term loans outstanding immediately prior to the amendment, (b) extend the maturity of such term loans to November 20, 2024 and (c) reprice the rates applicable to such term loans by amending the definitions of ABR, Applicable Margin and LIBOR Rate (each, as defined in the Credit Agreement). Pursuant to the joinder and amendment agreement, the initial new Applicable Margins are (i) 2.75% for the new first lien term loans that are LIBOR Loans (as defined in the Credit Agreement), which is 25 basis points lower than the previous interest rate margin and (ii) 1.75% for the new first lien term loans that are ABR Loans (as defined in the Credit Agreement), which is 25 basis points lower than the previous interest rate margin. The joinder and amendment agreement further provides that the above Applicable Margins for the new term loans will be based on NVI’s public corporate credit rating from Moody’s as follows: (i) if NVI’s rating is lower than Ba3 (stable), the Applicable Margin will be 2.75% for LIBOR Loans and 1.75% for ABR Loans and (ii) if NVI’s rating is Ba3 (stable) or better, the Applicable Margin will step down to 2.50% for LIBOR Loans and 1.5% for ABR Loans, as specified in the joinder and amendment agreement. KCM, Goldman Sachs Bank USA and Merrill Lynch, Pierce, Fenner & Smith Incorporated acted as joint lead arrangers with respect to the joinder and amendment agreement and in aggregate received fees of $0.7 million, of which $0.3 million was received by KCM.

Description of Business and Basis of Presentation (Policies)	9 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying condensed consolidated financial statements have been prepared by the Company in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and, therefore, do not include all information and footnotes required by U.S. GAAP for complete consolidated financial statements. The condensed consolidated balance sheet as of December 31, 2016 has been derived from the audited consolidated balance sheet for the fiscal year then ended. These unaudited interim condensed consolidated financial statements reflect all normal and recurring adjustments which are, in the opinion of management, necessary to present fairly the Company’s consolidated financial position as of September 30, 2017, the consolidated results of operations for the three and nine months ended September 30, 2017 and October 1, 2016, and consolidated cash flows for the nine months ended September 30, 2017 and October 1, 2016. Certain information and footnote disclosures normally included in our annual consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted; however, we believe that the disclosures included herein are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto for the fiscal year ended December 31, 2016 included in the Company’s final prospectus dated October 25, 2017 (the “Prospectus”), as filed with the Securities and Exchange Commission (the “SEC”) on October 27, 2017 pursuant to Rule 424(b)(4) under the Securities Act Securities Act of 1933, as amended (the “Securities Act”). The significant accounting policies followed by the Company are set forth in Note 1 within those consolidated financial statements. We use the same accounting policies in preparing interim condensed consolidated financial information and annual consolidated financial statements. There were no changes in our significant accounting policies during the nine months ended September 30, 2017, except for the adoption of Accounting Standards Update (“ASU”) No. 2016-09, Improvements to Employee Share-Based Payment Accounting and ASU No. 2017-04, Intangibles - Goodwill and Other, neither of which had a material effect on the Company’s consolidated financial condition, results of operations, or cash flows. The condensed consolidated financial statements include our accounts and those of our subsidiaries, all of which are wholly-owned. All intercompany balances and transactions have been eliminated in consolidation.
Fiscal Year	Fiscal Year Our fiscal year consists of 52 or 53 weeks ending on the Saturday closest to December 31. Fiscal year 2017 contains 52 weeks and will end on December 30, 2017. All three and nine month periods presented herein contain 13 and 39 weeks, respectively. All references to years and quarters relate to fiscal periods rather than calendar periods.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Deferred Offering Costs	Deferred Offering Costs We capitalize legal and accounting fees directly relating to the IPO. These deferred offering costs will be offset against offering proceeds during the fourth fiscal quarter of 2017.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, Revenue from Contracts with Customers, to clarify the principles used to recognize revenue for all entities. ASU No. 2014-09 provides new guidance related to the core principle that an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new guidance also will result in enhanced disclosures about revenue, provide guidance for transactions that were not previously addressed comprehensively, and improve guidance for multiple-element arrangements. During 2016, the FASB issued additional ASUs to clarify certain aspects of ASU No. 2014-09, including ASU No. 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) in March 2016, and ASU No. 2016-10, Identifying Performance Obligations and Licensing in April 2016. The guidance is effective for fiscal years beginning after December 15, 2017, and interim reporting periods within that fiscal year. The Company will adopt this new guidance in the first quarter of 2018 using the modified retrospective method. The most significant components of the new guidance to the Company relate to performance obligations surrounding our bundled product and service offerings and the reporting of revenue on a gross versus net basis with respect to our management and services agreement with Walmart, and the timing of revenue recognition associated with our discount club membership fees. We are currently finalizing our assessment, but we do not expect the adoption of this new guidance to have a significant impact on the timing or amount of revenue recognized in our consolidated financial results based on our implementation progress to-date. We do expect incremental additional disclosures in the notes to our consolidated financial statements. In February 2016, FASB issued ASU No. 2016-02, Leases. The new guidance establishes a right-of-use (“ROU”) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either financing or operating, with such classification affecting the pattern of expense recognition in the statement of operations. The guidance is effective for fiscal years beginning after December 15, 2018, and interim reporting periods within that fiscal year. A modified transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company will adopt this new guidance in the first quarter of 2019. We are evaluating the impact of implementation of this new guidance on our consolidated financial statements, but expect that adoption will have a material impact to the Company’s total assets and liabilities since we have a significant number of operating leases not currently recognized on our consolidated balance sheets. In April 2016, FASB issued ASU No. 2016-09, Improvements to Employee Share-Based Payment Accounting. This new guidance simplifies the accounting for share-based payment transactions, including income tax consequences, classification of certain items on the statement of cash flows, forfeitures, and minimum statutory withholding requirements. This new guidance is effective for fiscal years beginning after December 15, 2016, and interim reporting periods within that fiscal year. We adopted this new guidance in the first quarter of 2017. The adoption of this new guidance did not have a material effect on the Company’s financial condition, results of operations, or cash flows. In January 2017, FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other. This new guidance removes Step 2 of the goodwill impairment test. A goodwill impairment will now be the amount by which a reporting unit’s carrying value exceeds its fair value, not to exceed the carrying amount of goodwill. The new guidance will be applied prospectively, and is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We adopted this new guidance during the first quarter of 2017. The adoption of this new guidance did not have a material effect on the Company’s financial condition, results of operations, or cash flows.
